.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  youtube\-dl [options] url ...
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
youtube-dl is a script to download videos from youtube.com.
.PP
Once it is installed in your system, you should be able to call it from
the command line. Usage instructions are easy. Use youtube-dl followed
by a video \s-1URL\s0 or identifier. As an example, consider:
.PP
.Vb 1
\&  youtube\-dl "http://www.youtube.com/watch?v=foobar"
.Ve
.PP
The video will be saved to the file \f(CW\*(C`foobar.flv\*(C'\fR in that example. Many
YouTube.com videos are in Flash Video format and their extension would
be \f(CW\*(C`flv\*(C'\fR. Other videos are encoded in H.264 and these usually have the
extension \f(CW\*(C`mp4\*(C'\fR.  In Linux and other unices, video players using a
recent version of ffmpeg can play them. That includes MPlayer, \s-1VLC\s0,
xine, among others.

.SH "OUTPUT TEMPLATE"
.IX Header "OUTPUT TEMPLATE"
The \-o option allows users to indicate a template for the output file
names. The basic usage is not to set any template arguments when
downloading a single file, like in youtube-dl \-o funny_video.flv
\&\*(L"http://some/video\*(R". However, it may contain special sequences that will
be replaced when downloading each video.
.PP
The special sequences have the format \f(CW\*(C`%(NAME)s\*(C'\fR. To clarify, that's a
percent symbol followed by a name in parenthesis, followed by a
lowercase S. Allowed names are:
.IP "id" 4
.IX Item "id"
The sequence will be replaced by the video identifier.
.IP "url" 4
.IX Item "url"
The sequence will be replaced by the video \s-1URL\s0.

.IX Item "stitle"
The sequence will be replaced by a simplified video title, restricted to
alphanumeric characters and dashes.
.IP "ext" 4
.IX Item "ext"
The sequence will be replaced by the appropriate extension (like \f(CW\*(C`flv\*(C'\fR
or \f(CW\*(C`mp4\*(C'\fR).
.IP "epoch" 4
.IX Item "epoch"
The sequence will be replaced by the Unix epoch when creating the file.
.PP
As you may have guessed, the default template is \f(CW\*(C`%(id)s.%(ext)s\*(C'\fR. When
some command line options are used, it's replaced by other templates
like \f(CW\*(C`%(title)s\-%(id)s.%(ext)s\*(C'\fR. You can specify your own.
